Serial No. 467,558.

To @ZZ whom tt may concern:

Be it. known that I, FRANZ CARL JUNG- MANN, a citizen of the United States, and a resident of Portland, in the county of Mult-- nomah and State of Oregon, have invented a certain new and useful fml'novement in Music-Leaf Turners, of which the following is a specification, reference being had to the accompanying drawings as constituting a part thereof.

'This invention has for its object to obtain a music-leaf turning device of simple and inexpensive construction, reliable in its operation, and adapted to be applied to the rack of any music stand, or to a music rack of an instrument like the piano; and to this end my invention relatesI to the construction, arrangement and combination of parts hereinafter fully described and pointed outI in the claims.

ln the accompanying drawings of my invention: Figure 1 is a front elevation of my music-leaf turner; Fig. 2 is a partial front view, on enlarged scale, of the upper part of the supporting back-board of my device, showing in part the mechanical details whereby the turning of the music-leaf is accomplished; Fig. 3 is a top view of the same parts as shown in Fig. 2, and on the same scale; Figs. 4L and 5, taken together, show an elevation of what I term the leaffinger, which is affixed to the upper edge of the music sheet to be turned by my device; the parts of the leaf-finger being separated and their union, as in practice, being illustrated in Fig. 6, which shows an end view of the device last referred to; Figs. 7 and 8 are details of the means for fastening` the two parts of a leaf-linger together; Fig. 9 is a detail of a movable block supported on the bow-like rest over which travels the pivoted arm by which the turning of a leaf in one direction or the other is effected; Fig. 10 is a perspective detail of construction, illustrating means for securing in place the slidable bottom-rail of my device, on which rail the musical composition is supported on my rack; Figs. 11 and 12, taken together, show a detail of a pulley and guide over which the cords of the pivoted operating arm are guided; Fig. 13 is a detail of a reinforcing perforated plate, which may be used as part of the means for locking the slidable bottom-rail in place; and Fig. 14

is a detail of a clamp which may be used in connection with my device, the clamp being adapted to be fastened on the knee, and to have the ends of the cords by which my device is operated attached thereto.

Referring now to the letters in the several views: The back-board, a, may be made of any convenient material, and is provided on its upper face with vertical grooves b, atthe two ends, and horizontal grooves c, c at the top and bottom; the bottom grooves merely serving to give a uniformity to the appearance of the back-board. To the outer ends of the back-board are fastened guidebars, (Z, bent in right angle, the lower portions Z of which are spaced apart from the under surface of the back-board, a, so as to provide a space in which to receive the operating cords c, f, g, 7L. Guide-pulleys z', i are provided at the bottom of the backboard, onwthe under side, as shown in Fig. 1; said guide-pulleys being journaled in a boXj as shown in Figs. ll and 12. Like pulleys as z', z" are also provided at the top, viz: 2, 3, to guide the upper ends of the cords c, f, g, ZL. The guide-pulley z' is omitted from the detail Fig. 10. All the operating cords c, f, and g, 71, are lead through boxes like y' over said pulleys to prevent the cords getting oil the pulleys.

On the back-board is slidably mounted a bottoni-rail Z, provided at its lower end with a lip Z; and its two lateral ends are provided with clamping members Z2, having rightangle extensions Z3, embracing the members Z of the guide-bars (Z. The members Z3 of the rail, Z, are provided on their inner ends with lips Z4, formed by a return bend, and said lips ride on the edges, (Z2, of the members, cZ, of the guide rails CZ. The arrangement just described is more clearly shown in Fig. 10, and the purpose thereof is to give a steadiness and guidance to the rail Z, making it convenient to adjust the latter to any height on the back-board a. At the two ends of the rail, Z, are provided locking means for holding the rail, Z, in the position to which adjusted. These locking means are conveniently made of two spring arms m (see Fig. l0) fastened to the under side of the rail, Z, and provided with bent points m positioned over the vertical grooves Z), b. The back-board, a, being of wood, in order to lock the rail, Z, in the place to which adjustcd, it is but necessarv to bear on the rail, l. over the lockingl ineinbers m; and when desiring to niove the position of the rail Z, it only necessaryT to litt he ends oil" the rail, a tritle 'troni the back-board, a. so as to disengage the points m ot said lockinl ineinbers m.

in lig. 13 have shown a detail of perlorated plates 32, one ot' which inay be Ytastened over ach oi? the grooves l), 7) to save said grooves Ytroni wear. The locking points m ot the spring arins, m, would, under such circumstances. be inserted in the pei'torations of the plates Z22.

To hold the piece off inusic eurely on niy ack, I provide elastic cords n, n. n2, the cord n being` arranged at the center, and the cords 7a., n? being used to hold the cover. and those leaves ot the niusic sheet not Vto be turned. iirniljv in place. To seeure the bottoni ends of said eofds7 the rail Z is inade with notches Z5. lilhen the Cords n, n2, or either thereof, are not to be nsed, the saine may he arranged as illustrated of the Cord if, in Fig. l, that is, laid in one branch oiI the groove e.

)it the top of the bach-boa d, rz, aliixtal a bow-shaped rest o.

p is a short axle journaled between two plates 7). pi; and in the axle y) is pivoted an arin Q'. The ends of the Cords e, g, are liastened to the l:ile j) in such wise as to lie in the grooves p". See Fig. 2.

Un the rear of the back-l aard. at the top. are provided lo. Kes p', p2, in which are pivoted sniall rollers, as guiding nieans for the cordsI e, g, which are led over said rollers and thence over the pulleys 2, 3.

rit coil-spring is provided in the slit of the axleo'nenil'ier y), to bear on the arni y and norinally hold the saine down on the bow-rest o.

ivoted to the back-board7 o, are two laterally extending linge s s, s. having` each projectingends s2. Pivotally supported at the upper end ot the bach-boord are levers t, t, provided respectively with eyes t2, and controlled by a Coil-spring fu. rlhe ends ot the cords f. 7i, are fastened to eyes Z2 ot the levers t, as shown in Figs. l and 2.

rlhe function of the levers t, 2 is to litt one or the other ot' the 'lingers s, s, and thereb v disengapje the. arni y lroni the engaged le; itingrers fr, clainped on the to) edge ot the leaf. rfhe construction of said leaitinger. n,

is shown in Figs. et and 5. it comprises two pieces u, to. The piece a is inade with an extention o and is provided with lips r2, We adaiiited to be engaged b v the arin fj, as presently will be explained. rEhe pieee if* is i'urther iroxided with spring` clasps et, if. a detail of which is shown in Figs. T and S. The saine coinlvn'ising` a beari ig "l, ha ving;l

The 'ozn )anion-ineinber ot the leali-iinf consiy oi" a bar i," Yinovided with apertured lugs in adapted to receive the springt cl el, if', ind beingY locked h v ai'rang'ii clasp/ingl inen'ihers el. o in their pendent upset; that is to say. thrown over on its dde by the nnpaet ot the arni g' when thrfiwu against the extension e or one ol the lealbeing caused to drop behind the sai/.l lipsv by the iinpulse of the Coil-spring in to relieve the enit-spring i', one ot the cords* /L is pulled to op irate one oli the levers i', i. thereby lifting one of the lingers s, .f, and disengagingthe arin g' troni he 1ip i," or e ol. the leaitinger Q1. The :aine operation is also used to cause the arin f/ to be Vli'tted over the extension vi ot a leaf-tinge?, and permit the arin to be brought into engagement with the likel extension of another lea't-tingg'er. There a .'e as many Aleaif-tiiiejers ridi 1g on the bo v-rest, o, as there are leaves in the n'nisical eoniposition to be turned over.

it. is convenient to use in eonneetion with niy device a pair ot linee-clamps such as illustrated in Fig. l-l. consistingl ot a Llshaped si'iring-clanip. yu, adapted to l e elaniped on the linee and provided with hooks. fr. to which to tasten the ends o't the cords c, g/ and f, 71.. rlhat is to say, two o'lf the knee-clamps Vlike .fr would be used7 and on one ot theui the two ends ot the cords c, y, would be fastened, whereby the arin Y// is thrown to one side or the other, to turn the lea'f; and to the other lnee-elanip would be fastened the two ends ot the eords f, fl, whereby to worl; the lingers s. s. to disengage the arin g troni the leali-tinger7 and engage the saine with another, as above de4 scribed. Yhen the arni f/ has passed over the extension if" of one Vleat-tinger. l. it will be in position to engage with the adjacent leali-linger, and inay in turn be disengaged freni such adjaeent leali-linger and reen gaged with the lirst leali-finger, or with another leaf-linger. according to eireuinstances.

In Fie. 9 l have shown inovable blocks, y,

ind then droppino' behind one of the Cit llo

Cir

clamped by a set-screw y on the bow rest 0. The purpose of such blocks is to position the same in front of the leaves of the composition which are not to be turned, so as to receive the impact of the leaf-lingers when thrown one way or the other by the operation of the arm y, to turn over a music leaf. tn other words, they save wear and tear of the underlying leaves; and said blocks jl/ assure also a proper action of my device by providing an abutment for the leaf-fingers 1J to rest against when receiving the impact of the arm g, and thus also serving to prevent the throwing of the leaftinger over on its side, by such impact.
